The Western Australian School of Mines (WASM) has developed a facility for the static testing of full-scale ground support elements (Morton et al, 2007)._x000D_
The test facility consists of several stiff steel frames used to support the sample and a screw feed jack is used to load the sample._x000D_
A large-scale punch test method has been developed to load various shotcrete configurations. The shotcrete is sprayed on to a rock substrate containing a centrally located circular disc. The rock and shotcrete sample is placed on to the sample frame and restrained on all sides. The circular disc is displaced at a constant rate by the screw feed jack which in turn loads the sample._x000D_
Instrumentation measures the displacement and the load being applied to the sample through the loading disc._x000D_
The testing method is described in detail and the results from the testing program are presented. The results show that it is possible through laboratory testing to simulate some of the mechanisms of shotcrete support reactions better than conventional beam and panel tests.
